Legendary Wings

On every level, there will appear a grouping of 3 statues arranged in a triangular pattern about 3/4 of the way through. Drop bombs on them until they are destroyed, and one of them will reveal a passageway (note: the passageway will appear underneath a different statue every time) - now fly into the passageway. You'll be taken inside a cave. Collect the treasure chests which are worth 200 points each. DO NOT SHOOT INSIDE THE CAVE!!! If you fire and hit a treasure chest it will be destroyed, and parts of the cavern walls will release enemies when shot.
